ORE-SEPARATOR.

To all whom it may concern:

Be it. known that we, MALooM P. BATES and JOHN S. LA'MPTON, citizens of the United States, residing at Oceanpark, in the county of Los Angeles, State of California, have invented a new and useful. Ore- Separator, of which the following is a specification. This invention relates to machines for separating ore, one of itsobjects being to provide means whereby the gravel can be supplied to the machine directly from the pit without first being screened or concentrated, -there being means embodied within the machine for thoroughly separating the sand from the gravel after which the sand is discharged onto the ritlles provided therefor and the gravel is dumped from the machine, the various operations taking place automatically and in proper succession.

Another object is to provide means whereby the same water can be used during successive operations, thus reducing to the minimum the waste of valves. 7

With the foregoing and other objects in view which will appear as the description nation and arrangement of parts and in the details of construction hereinafter described changes in the precise embodiment of the invention herein disclosed can be made withparting from the spirit of the invention. In the accompanying drawings, the preferred form of the invention has been shown.

In said drawings :fFigure l is a side elevation of the machinepor'tions being shown in section. v Fig. 2 is an enlarged end elevation. F ig. 3 is an enlarged longitudinal section through the drum. Fig. t is a trans verse section through the bearing shaft at one side of the drum and showing a portion of the adjacent spider and the adjoining parts in elevation.

Referring to the figures by characters of reference 1 designates sills having an up standing fra1ne2 mounted thereon adj acent is interposed between the caps and has spiders 5. secured to the sides thereof, there being a trunnion 6 extending from one-of these spiders, andfjou1'naled in one ofthe Specification of Letters Patent.

that the frame t is free to swing about the 7 and trunnion 6. Each spider 5 has an arm 8 extending rearwardly therefrom and having a sleeve 9 pivotally con- These sleeves are adjustably engaged by the upper end portions of connecting rods 10 which, in turn, are pivotally attached to slides 11 mounted in guides 12. Anti-friction rollers 13 are carried by the lower ends of the slides 11 and are in constant engagement with cams 14 secured to a shaft 15. This shaft extends transversely of and is journaled upon the lower portion of. frame 2 and has a gear 16 at one end meshing with and adapted to be driven by .turn secured to a transverse shaft19 journaled in the lower portion of frame 2 and having a worm wheel 20 secured to one end thereof. Said worm wheel receives motion through a worm 21 from a line shaft 22 which may, if desired, have a pulley 23 at one end whereby the same may be driven by any suitable, motor.

Shaft 22 has a gear 24 meshing with and adapted to rotate a gear 25 which is secured to the lower end portion of an upstanding shaft 26 journaled in frame 2. This shaft has agear 27 at its upper end meshing with a gear 2S on the shaft 7. Another gear 29 is secured to .the inner end of'this shaft 17 and meshes with a toothed ring 30 secured to and extending around the middle portion of a drum 31. This drum is arranged within the frame 4 and has annular bearing rails 3.2 adjacent the ends thereofand which are I contacted by anti-friction rollers 33 carried by the frame 4:, these rollers serving to hold 51 the drum centered at all times within the frame. From the foregoing it will be apparent that when shaft 26 is rotated motion 27 and 28 to shaft 7 and gear 29 will there fore rotate the toothed ring 80 and the drum 31. llloreover the worm gearing 20., 21, and the gears 18, 1 7 and 16, will drive the shaft 15 and the-"cams 14; will therefore hold the rods 10 and the arms 8 elevated until after the drum 31 has beerrro-tated a number of times by means of the mechanism hereinbefo-re described, after which the cams will shift the rods 10 longitudinally and causes the frame 4 and the drum therein to swing:

downwardly and then upwardly at one end- ,will be transmitted therefrom through gears plate 39 respectively,

- Without, however, interfering with the rotation of the drum. Drum 31 is open atone end while its other end has a frusto-conical outlet portion 34; i

normally closed by a head 35. This head has a stem 36- projecting perpendicularly from the center thereof and slidably mounted in a guide 37 supported by an arm 38 pro.- jeoting from one end of the frame 4. A plate 39 is secured to the stem 36 and a spring 40. is mounted on the stem and bears at its ends against the guide 37 and the thus operating to hold the head normally in closed position. A

rock shaft 4:1 is journalediipon one end of the frame 4: and has arms 42 extending therefrom and movably engaging the plate l 39. Arms as extend from the endsor the shaftl and areconnected, by rodsAA to stantly engaged. y cams 418 secured to the shaftlii. .1he cams 14 and 18 are 'so shaped and timed that,.;at'ter the drum 31 has been" rotated 101' a predeterminedlength of'time avhile inclined as shown in Fig. 1, theshaft #1 will be rocked, by the bell crank levers45. atnutheir connections so as to cause the arms {L2 to push against collar 39'ando'p en the. head 35 against the stress of spring 40. The" head will be maintained openv a-suflicient 1 length of time to .permit the contents of the, drum to gravitate through the open'end of the dmm ai'ter' which the head will auto matically close and rods 10 will then pull'on the arms Sand'caus e the frame at and drum 31 to tilt so as to elevate its outlet or reduced end and permit the contents of the drum to gravitate out of thalarge or open end there of. The cams 14L Wlll then return the druml 31 and its frame 4; to its normal position, as

shown in Fig. "1, whereupon the foregoing. operation will be repeated, it being understood that the drum 31 continues to rotate throughout the tilting operation and during the movement of the head to open and to closed position. A tank or cistern 19 is located under the sills 1 and a centrifugal pump 50is mounted therein, its shaft 51 being extended up wardly into the frame 2 and provided with a pulley 52 receivingmotion, through a belt 53, from a pulley 54 on the shaft 26. -The inlet to the pump 50 is located close'to the bottom of the c{tank orcistern 19, as "indicated at 55'an the outlet pipe 56 extends up rdlyto'a coupling- 57 concentric With the gigot axis of the drum 31. Another pipe 5 is pivotally connected to this cou pling and discharges into the open large end of the drum 3-1, said pipe 58 being connected to and adapted to swing with the drum. l, 1-1.

Any desired number of'ribs59 are secured within the drum 31 and extend longitudina'lly" thereof, each rib being preferably formed of a' length offangle iron or the like. Moreover a diaphragm 60, preferably of perforated metal or of heavy metal fabricis the ends thereof, thus dividing the interior of the drum into two compartments,utrrWit, an upper or receiving compartment 6 1" and a lower ordelivering compartment 62.

A rifHe box 63Jis arranged on the sills 1 elevator boot 64 opening into and extending belowone end of this box. Both the riflle boxanfl the boot are water-tight.
